Title: Flush stool
Inventor: SATO YASUSHI
IPC: E03D11/18
Filed: 1998-06-25
Abstract: PROBLEM TO BE SOLVED: To provide a flush stool which makes it unnecessary to drain water in a larger quantity than the one of the water being water-sealed, on the occasion of draining the water in a bowl, and makes it also unnecessary to provide an opening-closing valve. SOLUTION: This flush stool is equipped with a trap introduction pipe 2 which is formed of a soft material to be extensible and contractible and introduces water discharged from a bowl 7 into a trap part 3. It is equipped with the trap part 3 which is formed of a hard material and so provided as to be movable vertically and with a trap lead-out pipe 4 which is formed of the soft material to be extensible and contractible and drains the water led out from the trap part 3. At an ordinary time, a height of the level of the water impounded in the bowl is regulated by the trap part so as to ensure the impounded water in the bowl. At the time of draining, the trap part is moved downward to make the trap introduction pipe and the trap lead-out pipe contract in the vertical direction.  Thereby the impounded water in the trap introduction pipe is made to overflow from the trap part and the impounded water in the bowl is drained by a siphon effect.

IPC: F01N3/24
Filed: 1997-07-03
Abstract: PROBLEM TO BE SOLVED: To prevent a reducing agent from being carried into an exhaust branched pipe having an exhaust gas circulating device mounted thereon by performing an exhausting stroke in a cylinder corresponding to the exhaust branch pipe having the exhaust gas circulating device mounted thereon when the reducing agent is supplied to a predetermined exhaust branch pipe. SOLUTION: In the exhausting stroke of each cylinder #1-#4 of an engine 1, an exhaust valve is opened over an angle larger than a crank angle of 180 deg.. Thus, the exhausting stroke of the cylinder #4 is started before the exhausting stroke of the cylinder #3 is ended, for example, the pressure in an exhaust branch pipe 7d and a collecting pipe 9 is increased when a purifying HC supplied from a fuel injection valve 2c reaches a downstream combining part 10 in the expanding stroke or exhausting stroke of the cylinder #3. According to this structure, when the exhaust gas within the exhaust branch pipe 7d is introduced into intake air through an exhaust circulating pipe 15, the purifying HC can be prevented from introduced into the intake air through the exhaust branch pipe 7d and the exhaust circulating pipe 15.

Title: Magnetic recording and reproducing device
Inventor: MASUI HIKARI
IPC: G11B15/473
Filed: 1987-07-20
Abstract: PURPOSE:To shorten the time required in leading the cylinder rotating speed to a target speed by changing over the control characteristic of a phase control system according to the rotation frequency of the cylinder at that time. CONSTITUTION:The output of the counter 7 of a speed control system and the aiming rotation frequency omega0 stored in ROM 16 are compared in a comparator 18. The output of the comparator 18 expressed whether the cylinder rotation frequency is higher or lower than the frequency omega0. In a comparator 15, also, the term when a detection characteristic is changed is detected by comparing the output of the phase control system counter 4 and that from the ROM 16 and outputted to a switch 17. Arithmetic circuits 13, 14 output the result substracting or adding the output of the counter 4 and that of the ROM 16 respectively. Two phase system detection characteristics are obtd. by the comparators 15, 18 and circuits 13, 14. Thus the phase error signal outputted from a latch circuit 5 becomes of a high level signal in case of the rotations being lower than omega0 and low level in case of higher than omega0.
